Abstract: ABSTRACT OF THE DISCLOSURE           A machine and method are provided for laying more than one layer of cementitious pavement simultaneously on a base surface.  The machine has a movable frame and a first receiving structure for receiving a first cementitious compo-sition in a plastic condition.  A first strike-off mechanism is provided for shaping a first cementitious composition in the first receiving structure by forming grooves in the top surface thereof.  Second receiving structure is attached to the frame behind the first receiving structure for receiving and depositing a second cementitious composition in a plastic condition on top of the first composition.  A second strike-off mechanism is then provided for leveling off the top of the second cementitious composition to form a two layer pavement of a desired thickness.          By the use of this apparatus according to the method provided, the two cementitious compositions form interlocking layers which dry together.  The layers of the concrete pavement are positively connected together to prevent relative movement between the layers.

Abstract: ABSTRACT OF THE DISCLOSURE In an exemplary embodiment a multiplexer unit is arranged in the first device unit in the input channels for electric physiological signals and a demultiplexer unit is arranged in the second device unit on the side of the output channels for the time-shared scanning of the signals in the input or, respectively, output channel; and a pulse amplitude modulator and a single galvanically separating coupling location are inserted in ceries between the multiplexer unit of the first device unit and the demultiplexer unit of the second device unit at the interface between both device units for the de-coupled signal transmission in the time multiplex mode.  By this arrangement the minimized number of coupling locations holds coupling capaci-tance and leakage current to a minimum with only a modest outlay for apper-taining control circuitry.

Abstract: ABSTRACT OF THE INVENTION A process for rendering actinide values recoverable from sodium carbonate scrub waste solutions containing these and other values along with organic compounds resulting from the radio-lytic and hydrolytic degradation of neutral organophosphorous extractants such as tri-n butyl phosphate (TEP) and dihexyl-N,N-diethyl carbamylmethylene phosphonate (DHDECMP) which have been used in the reprocessing of irradiated nuclear reactor fuels.  The scrub waste solution is preferably made acidic with mineral acid, to form a feed solution which is then contacted with a water-immiscible, highly polar organic extractant which selectively extracts the degradation products from the feed solu-tion.  The feed solution can then be processed to recover the actinides for storage or recycled back into the high-level waste process stream.  The extractant is recycled after stripping the degradation products with a neutral sodium carbonate solution.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus are provided herein for preparing hydraulic mortars or concretes.  The method includes adding a quantity of water to fine aggregate particles, e.g., to sand particles, to in-crease their water content.  A predetermined quantity of fine aggregate particles, e.g., such sand particles to which water has been added, are then sequentially supplied.  An impact force is applied to such fine aggregate particles. e.g. such sand particles, either before or after the water has been added thereto, the force being stronger than the adhesive force of the water to such particles, thereby to remove excess water therefrom.  A hydraulic substance, e.g. cement, is then mixed with the so-treated particles.  The hydraulic mortar or concrete prepared from such particles has small segregation and bleeding, and products prepared therefrom have excellent mechanical strength.

A control logic includes a resident program with a series of instructions for the operation of the appliance and a memory for storing data which is retrievable in response to actuation of the membrane switching devices so that the appliance operates in accordance with the resident program and the retrieved data.  A display panel includes various individual displays for indicating the selected cycle, optional event, time period for the one event of the cycle, and the time remaining in the selected cycle.  A method of controlling the operation of the appliance includes displaying a time period for and the time remaining in a selected cycle, continuously monitoring the membrane switching devices to detect user actuated changes in the operation of the appliance during the selected cycle, and during the selected cycle, disabling certain membrane switching devices to thereafter eliminate the possibility of user actuated changes associated with such disabled switching devices.

Abstract: ABSTRACT            A method of uninterrupted operation of a current supply installation, which via a charger in the form of a primary-switched rectifier with a transformer (16) charges a battery (28) and carries a load (30) when the operating voltage is available to a sufficient extent, but for a voltage drop or break in voltage automatically disconnects the battery from the charger and instead supplies the load with voltage from the battery. The battery voltage is hereby chopped into square wave form and transformed up via the secondary side (20) of the transformer (16) to the voltage required for the load (30). A diode (38) is suitably connected between the load (30) and battery (28), for allowing the battery voltage to act directly on the load as long as this voltage is sufficiently high.
